Abstract: 773,330. Electric signalling systems. DOBBIE McINNES, Ltd. Jan. 3, 1955 [Aug. 21, 1953], No. 23083/53. Class 40 (1). In a pressure indicator or recorder of the balanced diaphragm type in which the varying pressure to be measured, e.g. in an internalcombustion engine, is applied to one side of the diaphragm, and a static but usually adjustable pressure is applied to the other, an electrical signal being generated at the instant of the reversal of pressure upon the diaphragm, the signal in the form of a step wave is fed to the input A of a phase-inverter valve V5 and gives pulses on both make-and-break which are of the same sign after passing the rectifiers M1, M2. The negative pulses are amplified by V6 and cause V7, normally biased beyond cut-off, to conduct for the period of the pulse and energize the transformer B to produce a high voltage surge in the secondary and provide a spark at the gap D at the recording drum E. The series gap C prevents double sparking and F is a safety gap. An A.C. input may be applied to the input of V5 to provide a reference line on the record. In an alternative arrangement, Fig. 2 (not shown), a push-pull arrangement of valves is used. Specification 654,310, [Group XIX], is referred to.

Title: Improvements in or relating to ammunition supplying devices for pairs of guns mounted in turrets or the like
IPC: F41A9/35
Filed: 1935-08-16
Abstract: 442,485. Ammunition -supplying devices for ordnance. SCHNEIDER & CIE, 42, Rue d'Anjou, and COMPAGNIE DES FORGES ET ACIERIES DE LA MARINE ET D'HOMECOURT, 12, Rue de La Rochefoucauld, both in Paris. Aug. 16, 1935, No. 23107. Convention date, Nov. 28, 1934. [Class 92 (i)] Fixed ammunition is simultaneously supplied to twin guns 1 from a pair of loaders 25, 25a, Fig. 5, associated with each gun, each loader receiving a round of ammunition and being movable from a waiting position, shown in full lines, to a breech-loading position, shown in chain lines. Further, a single operating mechanism, such as gearing moved by a handle 41, enables a loader 25 of one gun to be moved simultaneously with the loader 25 of the other gun, the loaders 25a being then moved by the same mechanism after a change-over clutch has been operated. The invention is shown applied to guns fed from a fixed hoist and a trainable tilting cage 15, Fig. 4, as described in Specifications 404,878 and 409,215. The loaders are carried by arms 27 connected to longitudinal shafts 28 rotatable by the operating gearing in bearings which together with the bearings of the transverse operating shaft 29 are carried by U-shaped frames 5 surrounding the breech end of each gun. The shaft 29 is rotatable from either end by toothed gears 42, 43 connected with the handles 41. Clutch members 40 on the shaft 29 are slidable under the control of a rod 45 moved from either side of the guns by handles 56. The arrangement is such that, with the clutches engaged as shown in Fig. 5, diagonally-opposite loaders 25a are swung into and out of gun-loading position when the shaft 29 is rotated, the load being balanced, since one loader moves downwardly whilst the other moves upwardly. After sliding the clutch, the other loaders 25 are similarly moved. Arms 59, 61 fixed to the frames 5 limit the return movements of the loaders to the position shown in Fig. 5, in which they receive the rounds of ammunition transferred from the tilting holders 17, as described in the above-mentioned Specifications. Disconnectable couplings 52, 54 in the operating gearing, and in the shaft (not shown) cross-connecting the elevating-gears, permit of one gun being elevated and loaded independently of the other. The loaders are slotted to accommodate the ramming appliances.

Title: Improvements in the steering of bogie vehicles
IPC: B62D13/04
Filed: 1927-09-05
Abstract: 301,777. Jonkhoff, H. W. Sept. 5, 1927. Adjusting bogies for steering; deflectable axleends and intermediate connections therefor; steering.-In vehicles mounted on a bogie carriage or carriages provided with steerable wheels and having a pivot, gear, or other connection between the loading platform and the steering lever of the bogie to steer the steerable wheels initially independently of the angular position of the bogie, means are provided operable by the bogie to correct and neutralize any movement imparted to the said wheels due to the swivelling of the bogie relatively to the vehicle platform. In the construction shown the vehicle platform P is supported by a bogie B carried by steering wheels S and non-steering wheels F. The stub axles of the wheels S are connected by links A to a rotary member M controlled by the drawbar D. In the position shown in Fig. 2 the drawbar has been deflected 18‹ and has rotated M through 9‹, causing the steering wheels to be deflected as shown. As the vehicle moves along this curved path the bogie swivels into the position shown in Fig. 3, but the connection between the drawbar and the member M is such that the wheels S remain in the same position relatively to the vehicle platform P as in Fig. 2. The mechanism connecting the drawbar and the member M is shown in Fig. 5, in which a member 1 is carried by the platform P and is concentric with a pivot member 2 fixed to the bogie frame B. The drawbar D pivots on the member 2 and is normally locked by a pin 7 to a bevel wheel 6 gearing with planet pinions 8 rotating on spindles carried by the member 1. A loose double bevel wheel 9 engages with the planet pinions 8 and with planet pinions 10 carried by the member M controlling the steering wheels. Thus when the drawbar is rotated through a certain angle the member M is rotated through half that angle and in the opposite direction. The bogie pivot member 2 is formed with a toothed quadrant 12 connected by gearing 13, 14 with a bevel wheel 15 engaging the undersides of the planet pinions 10, so that when the bogie rotates relatively to the platform the member M is rotated to re-adjust the steering wheels and counteract the rotation of the bogie. When the bogie, instead of being a leading bogie, is a trailing one, the pin 7 is withdrawn by means of a lever XY, thus freeing the gear from the drawbar, and the end Y of the lever catches in a notch 4<*> in the member M, thus locking the platform 1 and member M together.
